Focal length formula mirror
WebNov 22, 2024 · The relationship between the image distance, object distance, and focal length in spherical mirrors is given by the mirror equation, 1 do + 1 d = 1 f 1 d o + 1 d i = 1 f, where do d o is... WebNov 1, 2024 · A mirror's radius of curvature is the radius of the sphere it is a part of. The focal length, f f, of a mirror is always half of its radius of curvature, r r: \quad f = \frac {r} {2} f = 2r Hence, we can also write the mirror equation as follows: \quad \frac {2} {r}=\frac {1} {v} + \frac {1} {u} r2 = v1 + u1
